To test your IC-Tester, you need to introduce error on your chip. one way to do that is to disconnect a random input pin to simulate a broken pin on your chip. For that case, you can put a pushbutton between the output from Arduino and the input to your chip like figure 2. When running the circuit, you can push the button and disconnect your input. These pushbuttons act like wire when up and are open circuit when pushed (They should be connected to VDD to function)

Figure 2 is only an example and it is supposed that your board outputs a signal from digital pin 12 to pin 1b of your AND. Place two pushbuttons for two random inputs from two different gates of your chip and show your IC-tester can detect the error. Take a short video and upload here.
